Level 5: SCC: Dermoscopic Features associated with SCC:

See chapter on SCC for definitions.

• Scale (rough texture) is present in almost all lesions
• Glomerular (coiled) vessels
  • Focally distributed towards the periphery
  • Diffusely present throughout lesion
  • Aligned linearly within lesion
• White circles
• Brown circles
• Rosettes (seen with polarized light)
• Brown dots aligned in a linear fashion
• Strawberry pattern seen in actinic keratosis (AK)
• Hairpin (looped) vessels with a white halo can be seen in keratoacanthomas (KA). In KA these looped-vessels tend to be aligned at the periphery.
• Polymorphous vascular pattern composed of dotted, short linear and long linear irregular (serpentine) vessels.
